About Em and Lewis. If Em had said yes, i don't think he would have fucked her without Lisa being there. That is why i think Lisa wanted him to fuck Em. Maybe she brought Lewis to fuck Em not her. I say this because of the way they came in at 7 am, Lisa asking him not to talk loud, the way lisa woke Em up while Sid was sleeping and brought her to the loggia to talk, then they went to the sleeping room and Lewis started asking Em to have sex with him.
I don't think he would have dared to do that if Lisa and him hadden talked about it before they came in.
I think Em needs some time. We haven't seen a lot from her. But i think she's doing well.
